Dang! Just when I think I understand this acquisition thing. ;) Sorry for the misinformation. --jfarr "Perl is worse than Python because people wanted it worse."

Is it possible to have just one top level object that refers to other objects that get overridden as you go into other folders?
Acquisition works the other way around. You can create objects in subfolders whose contents are overriden higher up. You can't have an object at the top whose contents get overridden as you go down.
Urm, I think wires are getting crossed here, so here's an example which may help (and which we use on most of our sites):
index_html is a DTML method:
<dtml-var standard_html_header> <dtml-var index.html> <dtml-var standard_html_footer>
Now, in each folder we have DTML documents called index.html which actually contain the pages.
So, we have one index_html and many index.html's.
When someone does http://www.mysite.com/folder/ This actually renders http://www.mysite.com/folder/index_html Then, index_html is acquired from the root. However, because index.html exists is /folder, it is that which is displayed.
I hope this makes it a little clearer :S
cheers,
Chris
PS:
Your solution was correct. Create another index_html in the subfolder,
As long as index_html is a method, you only need one of them, in the root.
which uses the 'contents' object in the subfolder,
This will still happen if there's only one index_html
